The Outcome of Purse-string Versus Conventional Wound Closure Techniques in Patients Undergoing Stoma Reversal: A Randomized Controlled Trial

Background: Patients undergoing stoma reversal may experience surgical site infections and poor scarring. A purse -string closure approach may lower the incidence of surgical site infections due to its inherent ability to drain wound exudates. This study compared the frequency of surgical site infections and the cosmetic outlook of the scar among patients undergoing stoma reversal with linear and pursestring skin closure techniques. Setting and duration: Department of Pediatric Surgery, University of Child Health Sciences Lahore with a duration of one year (June 2021 to June 2022). Methods: This randomized controlled trial (TCTR20210417001) was conducted with IRB approval. A total of 124 patients undergoing stoma reversal were randomly assigned to two groups (62 in each): Group A received conventional linear skin closure, while Group B received purse -string wound closure. The study evaluated surgical site infection, cosmetic outcome, and length of stay. Results: Both groups had similar age, gender ratio, indication for surgery, and length of stay. The pursestring group had a significantly lower incidence of SSI (38.7 % vs. 14.5 %; p 1/4 0.002) and better scar quality (Manchester scar scale showed 'good' scar quality in 63 % of patients vs. 22.6 % in the linear closure group, p -value <0.0001). Conclusion: The purse -string technique for skin closure resulted in fewer surgical site infections and improved scar appearance. (c) 2023 Elsevier Inc. All rights reserved.
